The song was commissioned by the CBC in 1967 to mark Canada's centennial year and it has been a classic ever since. It eloquently describes the construction of the Canadian Pacific Railway -- "an iron road runnin' from the sea to the sea" -- a great feat of nation building that changed Canada forever for good and for ill, as in the process many people died and were dispossessed of their land.

Highly acclaimed, award-winning illustrator Ian Wallace brings the song to visual life with his sweeping landscapes and evocative portrayals of the people who lived the building of the railroad -- from the financiers in the east to First Nations people across the country to the thousands of navvies themselves, many of whom came from as far away as China.
